Jimmy Savile spent decades as one of Britain's most recognizable television hosts, fronting shows like Jim'll Fix It while using that fame to gain access to hospitals, schools, and the BBC's own studios. This film follows former police detective Mark Williams-Thomas as he builds the case that Savile used that access to abuse teenage girls for years, largely unchallenged. Williams-Thomas interviews victims directly, letting them describe what happened and how their complaints were ignored or dismissed, and he pairs their accounts with previously unseen footage of Savile himself. Experts on institutional failure add context on how hospitals, care homes, and the BBC allowed a public figure that much unsupervised contact with children. The film does not treat Savile's crimes as an isolated case of one predator; it treats them as a case study in how fame and charitable work bought him cover, and how many separate institutions had reason to know and did not act. The account is plain and evidentiary rather than sensational, built on testimony and documentation.
